R25,R28,R32, R38, T38, T45, T51, ST58, ST68, ac ati.
Nodwedd:
1. treiddiad drilio ardderchog
2. Defnyddir mewn ffurfio creigiau caled iawn neu anoddaf
3. Digonol ar gyfer amodau adeiladu amrywiol
4. cryf cyrydu ymwrthedd
Cais:
1. Mae'r bit croes yn addas ar gyfer cloddio ffurfiad creigiau caled iawn, ffurfio caled a ffurfio crac.
2. Mae'n rhaid ail-lanio pob darn croes yn rheolaidd i falu'r graig yn effeithlon.
3. Rydym yn dewis gwahanol ddeunydd a maint ar gyfer y darnau croes er mwyn addasu'r gwahanol ffurfiannau creigiau a
